I’m a full-stack developer focused on React, TypeScript, React Native, and Node.js. I build real products that solve real problems, and I enjoy working autonomously to ship useful features end-to-end.

Since May 2024, I’ve worked as a Freelance Full-Stack Developer building offline-first mobile apps with React Native, Expo, SQLite, and Ed25519 cryptographic QR validation. I also developed REST APIs with Node.js, Fastify, and Prisma connected to PostgreSQL, delivering secure authentication with JWT, bcrypt, refresh tokens, and brute-force protection.

I care about quality and clarity in how software is developed. I’ve created AI-augmented development workflows combining TDD, structured prompt systems, and AI pair programming, and I can confidently deliver in Scrum-style sprints.

My projects reflect the way I like to work: UberTrance Driver brings offline operation with automatic background sync and robust QR validation; FlowManager is a TDD-driven project management tool with 111 documented user stories; and Arena POC covers QR scanning, loyalty stamps, and role-based routing. I’m open to remote opportunities worldwide and fluent in English.
